The Science
Black turtle beans are high in fiber (55% DV per 100g) and protein (43% DV), which can slow carbohydrate absorption and improve glycemic control. However, they also contain 23% DV of carbohydrates per 100g, and the high calorie density (1417 cal/100g) could lead to weight gain if portion sizes are not managed, which is a risk for diabetes management. The minerals like magnesium (38% DV) may support insulin sensitivity, but overall suitability depends on portion control and total daily carb intake.
Recommendation
Include black turtle beans in moderate portions (e.g., 1/2 cup cooked) as part of a balanced meal, and monitor blood glucose response to adjust serving size.
